Endodontics – root canal treatment

Endodontics is a specialized field of dentistry that deals with the prevention, diagnosis, and treatment of diseases of the dental pulp and the surrounding tissues of the tooth root. One of the most well-known endodontic procedures is root canal therapy.

This procedure is necessary when the dental pulp, which contains the tooth nerve and blood vessels, is damaged or infected. The treatment is aimed at removing the infected or dead tissue inside the root and then filling this space with a biocompatible material. Endodontic treatment of a tooth is extremely important as it allows the natural tooth to be preserved, which might otherwise be lost due to disease or injury.

Who is an endodontist?

An endodontist is a dental specialist who has received further training and specialization in endodontics after basic dental education. His main tasks include the diagnosis, prevention, and treatment of diseases of the dental pulp and the surrounding tissues of the root canals. This means that the endodontist intervenes inside the tooth, especially when it is necessary to carry out root canal treatment.

Why do we need endodontic root canal treatment?

Endodontic treatment of a tooth is essential when the root canal system is inflamed, damaged, or infected. This can happen due to deep tooth decay, multiple dental procedures on the same tooth, a crack in the tooth, or an impact injury to the tooth. If left untreated, this condition can cause pain, abscess, or even tooth loss. Endodontic treatment of the tooth allows the root of the tooth to be cleaned and shaped, and then the root canal is filled to prevent further infection and to keep the tooth. This procedure not only eliminates pain and discomfort but also ensures that the tooth can be preserved instead of being extracted.

Signs that you need an endodontic examination and endodontic treatment:

The dental pulp, located in the center of the tooth, is made up of nerves and blood vessels. When the pulp is damaged or infected, endodontic treatment is often the only way to save the tooth. Some of the key signs that indicate the need for an endodontic examination and possible root canal treatment include:

  • Severe pain when chewing or applying pressure: This pain is often caused by inflammation or infection of the dental pulp and is a sign that the dental pulp is damaged.

  • Sensitivity to heat or cold: If sensitivity to temperature changes does not subside after the stimulus is removed or persists for an unusually long time, it may be a sign of deep tooth decay or root canal inflammation.

  • Swelling and pain in the gum around the affected tooth: Swelling can be a sign of pus build-up, which is caused by bacterial infection and root canal inflammation.

  • Darkening or staining of the tooth: Permanent discoloration of the tooth can be caused by damage or breakage of the tooth pulp, so treatment of the tooth is urgently needed.

  • Prolonged or recurrent pain: persistent pain or discomfort that does not go away over time or is recurrent can be a sign that the dental pulp is damaged.

  • Abscess formation: this is a purulent discharge that can appear on the gums in response to a bacterial infection, which can be assessed by a qualified endodontist.

If you notice any of the above symptoms, it is advisable to get help from an endodontist as soon as possible. Identifying and treating problems early can help preserve your tooth and prevent the spread of infection to surrounding tissues.

Causes of root canal treatment

The causes of root canal treatment are multifaceted and usually stem from problems related to the dental pulp or the root canal area. The most common cause is deep tooth decay that has reached the pulp and caused inflammation or infection. In addition, trauma to the tooth, for example from impact, can cause problems that may require treatment of the tooth. Multiple dental procedures on the same tooth or cracks in the tooth enamel can also compromise the pulp and require root canal treatment.

Preparing for an endodontic procedure

Before undergoing endodontic treatment, it is important to be well-informed about the procedure and any specifics of the treatment. Your dentist or endodontist will assess the extent of the problem by talking to you and taking an X-ray of the tooth, and advise you on the best approach.

It is advisable to avoid alcohol and smoking before the procedure, as they can affect healing and recovery. The endodontist will usually prescribe antibiotics or painkillers, which should be started a day or two before the procedure. It is also important that you eat as normal on the day of the procedure unless the endodontist advises you otherwise. Finally, be prepared that you may need a few days of rest after the procedure, so give yourself time to recover.

The importance of quality endodontic treatment of the tooth

Quality endodontic treatment is essential to maintain the health and functionality of the tooth. Tooth decay drastically increases the risk of tooth loss. Well-performed endodontic treatment not only removes infected or damaged tissue but also prevents re-infection.

A tooth that has been successfully treated can last a lifetime with good oral hygiene and regular dental check-ups. Conversely, poorly carried out treatment can lead to re-infection, an inflamed root canal, pain, and ultimately the need for tooth extraction.

How is endodontic treatment performed?

Endodontic treatment is essential to prevent tooth loss and relieve pain. Treatment of a tooth usually takes place in the following steps:

  1. Diagnosis: It all starts with an accurate diagnosis. The dentist or endodontist will use X-rays to look at the shape of the root canals and check for any signs of infection in the surrounding bone.

  2. Local anesthesia: Before the procedure starts, a local anesthetic will be applied to the affected area to ensure that the procedure is as painless as possible.

  3. Root canal access: A small opening is made at the top of the tooth through which the dentist will access the root canals.

  4. Root canal cleaning: The damaged or infected tooth pulp is removed, and then the root canals are cleaned, widened, and shaped in preparation for filling.

  5. Filling: After cleaning, the root canals are filled with a special material that prevents re-infection.

  6. Follow-up care: After endodontic treatment, it is important to follow up regularly with your dentist and maintain good oral hygiene to ensure the long-term health and functionality of the tooth.

Although endodontic treatment can seem intimidating at first, with modern techniques and anesthesia, the procedure is quite comfortable and successful in the vast majority of cases.

What is the success rate of endodontic treatment?

Endodontic treatment is a procedure with a success rate ranging from 85% to 97%, depending on the specific circumstances and the case. The key to a successful endodontic treatment is an accurate diagnosis, the use of modern techniques and equipment, and a carefully performed procedure, all of which are taken care of by an experienced endodontist at OrthoDental.

Can endodontic treatment save every tooth?

Although endodontic treatment is very effective, there are cases when a tooth cannot be saved. This can happen if the tooth is too damaged, or if the infection is too widespread, or if the root canals are not accessible. However, in most cases, with the right approach, the tooth can be successfully treated and preserved.

Does endodontic treatment hurt?

With modern techniques and local anesthesia, most endodontic procedures are minimally painful or completely painless. Most patients report that the sensation during the procedure is comparable to that of a conventional tooth filling. There may be a few days of sensitivity or discomfort after the procedure, but this can usually be managed with over-the-counter painkillers.

Recovery after endodontic treatment

After endodontic treatment, it is normal to feel some tenderness or mild pain in the affected tooth and surrounding tissues. It is important to avoid chewing or biting with the affected tooth until it is fully restored. It is also advisable to follow any instructions given to you by the endodontist regarding oral hygiene and any further treatment.

Endodontic re-treatment and possible complications after endodontic treatment

Although endodontic treatment is mostly successful, there are cases when a tooth does not heal completely after the procedure or develops a re-infection over time. In such cases, it may be necessary to re-treat or even undergo a surgical procedure, under the guidance of an endodontist, to remove part of the root or infected tissue. Possible complications after endodontic treatment include pain, swelling, infection, or abscess. However, with proper technique, care, and regular follow-up, most endodontic treatments are successful in the long term, and it is important that the procedure is carried out by an experienced endodontist. When the inflammation of the tooth is too advanced to be treated, our experts will advise you to replace the tooth with an affordable dental implant. You can read more about it in our article on the price of a dental implant.
